“…Nevertheless, the solid–liquid separation after the reactions was comparable to that of the previous work using the same reactor, in which the product yields were found to be generally greater than 0.9. 56 Based on the basic behaviors revealed in this study, further investigation including detailed evaluation of yields is currently in progress and the results will be reported elsewhere.…”

Synthesis of Nanocrystalline PuO2 by Hydrothermal and Thermal Decomposition of Pu(IV) Oxalate: A Comparative Study

et al. 2023

In recent years, the hydrothermal conversion of actinide (IV) oxalates into nanometric actinide dioxides (AnO2) has begun to be investigated as an alternative to the widely implemented thermal decomposition method. We present here a comparison between the hydrothermal and the conventional thermal decomposition of Pu(IV) oxalate in terms of particle size, morphology and residual carbon content. A parametric study was carried out in order to define the temperature and time applied in the hydrothermal conversion of tetravalent Pu-oxalate into PuO2 and to optimize the reaction conditions.
